Stone tool

Stone tools are tools made of stone. They are the reason the stone age was given its name. They were the first tools used by mankind, and were used by all human species, such as Homo habilis and Homo erectus. Recently it was learned that stone tools were used before the genusHomo evolved. These oldest tools come from the shores of Lake Turkana in Kenya, and date to 3.3 million years ago. They are 700,000 years older than any tools found before.[1]
